Corrosion and Protection | Year: 2013

The corrosion reason of outlet pipe for preheating stage in a methanol reformer was analyzed by means of macrography, thickness testing, chemical composition analysis, metallographic examination and corrosion product analysis. The results show that metal dusting caused by carbonization was the main reason for the pipeline corrosion thinning. Some suggestions about the materials selecton and technology improvement measures were proposed.
